Once Upon A Time star Jamie Chung has opened up about her latest wedding plans with fiancé Bryan Greenberg.

"We love working out," the 30-year-old told PEOPLE. "We love the outdoors. So we want to incorporate that — maybe make it a weekend and have all the guests go on a hike. Or there's a crazy obstacle course at this one location. It's going to be a fun wedding."

The wedding may take place in autumn 2015, she said, but Jamie, who admits the proposal was "a total surprise," is keen to take one step at a time.

"We just want to enjoy the year of being engaged," she said. "I think it really is stress-induced in terms of planning a wedding, but we've kind of initiated the conversation. I think the sooner you start, the less stressed out you're going to be."
